High-order harmonic generation in the presence of a resonance [PDF]

Physical Review A, 2011
We investigate high-order harmonic generation from laser-irradiated systems that support a shape resonance. From the numerical solution of the time-dependent Schrödinger equation, we calculate the harmonic spectra and the time-frequency analysis of the harmonic intensity and phase.

Immunosuppressive Drug Use in Limited Systemic Sclerosis: An International Survey

Arthritis Care &Research, EarlyView.
Objective Current guidelines recommend immunosuppressive treatment for diffuse cutaneous systemic sclerosis but are less clear on their use in limited cutaneous systemic sclerosis (lcSSc) in the absence of internal organ complications. We conducted an international survey to understand current immunosuppressive drug prescribing patterns in lcSSc ...

Key Resonance Component Evaluation of Medium-Voltage Power Systems

Zhongguo dianli
Modal analysis techniques can capture the most comprehensive harmonic resonance data. Although current sensitivity analysis methodologies can rank the impact that each electronic component has on resonance, they fall short in precisely pinpointing the ...

The Lupus Damage Index Revision Program: Results From the Item Generation and Reduction Phases

Arthritis Care &Research, EarlyView.
Objective A data‐driven and expert/patient consensus‐based project to develop a revised Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology (ACR) Damage Index (SDI) is under way supported by SLICC, ACR, and the Lupus Foundation of America. Our objective is to report the item generation and reduction phase results

Unified Harmonic Resonance

, 2005
This publication summarizes a series of experiments that reverse-engineer Nikola Tesla’s theoretical wireless-energy grid using acoustic analysis. By translating Tesla’s resonant 3-6-9 structure into controlled audio frequencies, the study demonstrates measurable harmonic coherence, phase stability, and geometric symmetry identical to Tesla’s predicted

From Adult to Adolescent: Alignment in Clinical Trials and Outcomes in Axial Spondyloarthritis

Arthritis Care &Research, EarlyView.
Spondyloarthritis (SpA) is a group of chronic inflammatory diseases encompassing axial and peripheral forms, with up to 20% of patients developing symptoms before age 16. Despite this substantial pediatric burden, treatment options for juvenile‐onset SpA (JSpA), particularly those with axial disease (axJSpA), remain limited.

An optimal design method of the resonant-free C-type filter

电力工程技术
Configuring a reactive power compensation capacitors as a resonant-free C-type filter is a common method to suppress reactive power compensation capacitors resonance. It can also be used to reduce the amplification of harmonic voltage caused by resonance
